| 英文摘要 | Chiral phase transition for three-flavor n-f = 2 + 1 qcd with m(u) = m(d) not equal m(s)., is investigated in a modified soft-wall holographic qcd model. solving temperature dependent chiral condensates from equations of motion of the modified soft-wall model, we extract the quark mass dependence of the order of chiral phase transition in the case of n-f = 2 + 1, and the result is in agreement with the "columbia plot", which is summarized from lattice simulations and other non-perturbative methods. first order phase transition is observed around the three flavor chiral limit m(u/d) = 0, m(s) = 0, while at sufficient large quark masses it turns to be a crossover phase transition. the first order and crossover regions are separated by a second order phase transition line. the second order line is divided into two parts by the mum = ms line, and the ms dependence of the transition temperature in these two parts are totally contrast, which might indicate that the two parts are governed by different universality classes. |
